The Relationship Between Foveal Sensitivity and Visual Acuity in Pediatric Idiopathic Intracranial Hypertension

Idiopathic intracranial hypertension (IIH) in children has the potential to cause profound and permanent vision loss. Several factors have been shown to correlate with visual acuity, but none thus far have examined the relationship between foveal sensitivity (reported as foveal threshold by Humphrey visual field testing) and visual acuity in children. Because foveal sensitivity is established early in the course of testing, it may be a more reliable and predictable measure of visual function in children compared to other parameters.
